A new class of bifunctionallinchpins bearing electrophilic sites β or γ to a silyl group have been designed, synthesized, and demonstrated to be competent in tricomponent unions exploiting Type II AnionRelayChemistry (ARC). High diastereoselectivities were observed when a phenyl moiety (R2) served as an anion-stabilizing group (ASG) adjacent to a methyl susbtituent (R1), while diastereomeric mixtures
